The present invention pertains A cooling system for a gas engine piston, the system comprising a cooling oil supply configured to feed a cooling oil flow to the gas engine piston, and a control device configured to control the cooling oil flow based at least on a predetermined parameter. The present invention further pertains to a gas engine comprising at least one gas engine piston and a cooling system according to any of the previous claims, wherein the gas engine piston is configured to be operable with at least one combustion gas. In addition, the present disclosure pertains to a cooling method for a gas engine piston, comprising the steps of receiving at least one predetermined parameter at the control device; controlling the cooling oil flow based on at least the predetermined parameter; and observing a sufficient cooling oil flow fed to the gas engine piston.

The invention relates to a method for operating an internal combustion engine, and air/gas mixture being introduced into the working chamber thereof and ignited by means of an ignition system. The above is carried out whereby the air/gas mixture is at least temporarily enriched. A channel () is let into the cylinder head () from a cylinder head external wall into the working chamber () or a pre-combustion chamber and a gas or a gas/air mixture may be introduced in a controlled manner into the working chamber () or the pre-combustion chamber, by means of said channel (). According to the invention, the above embodiment or method permits the cycle variations in the combustion pressure to be avoided.
